HARMONIC RESOLUTION SYSTEMS
VORTEX
Introduction
Thank you for purchasing the Harmonic Resolution Systems Vortex. When used properly, they will give you many years of superior
musical or video signal reproduction. The HRS Vortex is designed to significantly reduce the negative impact of air and structure-
borne vibration on your audio or video component performance. The Vortex is specifically designed for use with components that
have stiffer (plate and billet) metal chassis construction and yields targeted performance improvements when used in conjunction
with the HRS isolation bases. The HRS Vortex was designed specifically for used in combination with the HRS Isolation Bases.
Using the HRS Vortex in conjunction with another shelf that does not have the same capabilities as the HRS Isolation Bases could
limit the performance benefits achieved by the HRS Vortex. The HRS Vortex can be used in combination with the HRS Damping
Plates. While the Vortex significantly reduces bottom chassis noise, the Damping Plates will work to reduce top chassis noise if
present in the component.
Safety Instructions IMPORTANT!
Do not place the Vortex over ventilation holes of any electronic component. The ventilation holes will be blocked and the internal
operating temperature of the component may be increased.
Set Up Instructions
The HRS Vortex should be placed directly on the HRS Isolation Base supporting your component. HRS recommends using a pattern
of at least three HRS Vortexes to support a component. If the component is larger (over 100 sq inch), using four or five Vortexes
will often significantly improve performance. The HRS vortex was design to provide exceptional performance on a standard size
component using the 4 vortex set up. See the diagrams below for the recommended Vortex placements. HRS recommends that
every Vortex beyond the third unit is the model with adjustable height (example V150A, all adjustable Models have “A” at end of
model number). The bottom chassis (not the feet) of the component should be placed in direct contact with the HRS Vortex. The
point of the vortex is to be placed in contact with the HRS Isolation Base surface. Proper setup and contact with the chassis will
control bottom panel resonance and transfer energy from the chassis into the Vortex energy dissipation system. Moving the
Vortexes in small increments to find optimal performance for a specific component chassis based on listening tests is often
beneficial but the general guide shown below is excellent starting point. IF you have a drive, motor, or other noise source inside
the unit then placing the closest vortex directly under the noise source is often excellent starting location as well.
When setting up adjustable Vortexes HRS recommends placing them towards the front of the component for easy access. Use the
1/8” T-wrench (provided by HRS) to set the height of the adjustable Vortex model. Start with the adjustable Vortex just slightly
shorter than the non-adjustable model, then with the component placed on top of all the Vortexes, turn (using the wrench inserted
into one of the four catch holes on the adjustable center element) the adjustable vortex center element counter clockwise (viewed
from below vortex) to raise the Adjustable Vortex until in contacts the chassis and resist movement equally (this means there is
equal pressure on the chassis at all locations).You can easily check the pressure by conducting a simple test at each Vortex
location. Pushing on outside diameter of each vortex and observe the resistance to movement relative to the chassis. When there is
equal resistance to relative motion between the Vortex and the Chassis then there is the desired equal contact pressure at each
location.
